Are your users tired of having to enter their email addresses each time they sign in to a Webex site? Enable the Remember Me setting in Webex Control Hub so that Webex remembers your users for a configurable period.
From the customer view in https://admin.webex.com, go to Settings and scroll down to the Authentication section.
Toggle the switch under Remember Me Controls to on.
Set the number of days before users have to reenter their email address.
The browser sets a cookie, containing the hashed email address, to expire at the end of the configured period.
